BGE patch: Add min/max parameters to orientation constraint actuator

The min/max parameters define a minimum/maximum angle
that the object axis can have with the reference 
direction without being constrainted. The angle is 
expressed in degree and is limited to 0-180 range. 
The min/max parameters define a conical free zone
around the reference direction.

If the object axis is outside that free zone, the
actuator will tend to put it back using as a temporary
reference direction the vector that is exactly at
min or max degree of the reference direction 
(depending if the axis angle is below the minimum 
or above the maximum) and is located in the plane 
formed by the axis and the reference direction.

With a low damping value, this is equivalent to 
clamping the axis orientation within min/max degree
of the reference direction.

Backward compatibility corresponds to the absence
of free zone: min = max = 0.
